How tricky would this be to machine? I guess a Triac is not up to the job!

Hi magicniner, thanks for the reasurance I hope to get a little lathe oneday and try my hand at 316 on that.
Many thanks
Steve

Steve, With carbide tooling on a lathe 316 is quite sweet to work with, I don't know why people get steamed up about it ;-) - Nick
